(US4940387-A)      At least one water turbine (11) is located in the path of a water source for power generation. A barrage structure (10) extends across and above the level of the water source (12). The structure is of a cross-sectional width sufficient to absorb static and dynamic loading from the water source and defines only a draught tube (15) for the turbine. The turbine is mounted within an inlet casing (19) to form a separate assembly. The outlet end of the inlet casing is adapted to be releasably connected to the inlet end of the draught tube. Locating and locking members (24,25) are provided for effecting the releasable connection. Members (20 to 22) are provided for supporting the weight of the turbine/inlet casing assembly when connected to the draught tube.    Pref. the support for the turbine comprises a support pier (20) extending upwardly from the wall of the inlet casing to beneath the This assembly is, in turn, supported by a further support comprising a foundation pad (21) mounted on the support member (22). The turbine in use will transmit static and dynamic loading to the piling via the support structure.    USE -   Water turbine arrangement for power generation, esp.    for tidal water. (-pp)o    (GB2218742-B)      A water turbine arrangement in which at least one water turbine is located in the path of a water source for power generation, comprising a barrage structure which extends across and above the level of the water source, wherein the structure is of a cross-sectional width sufficient to absorb static and dynamic loading from said water source and defines only an outlet or draught tube for the turbine, the turbine is mounted centrally within an annular inlet casing to form a separate turbine assembly, the turbine assembly has a support structure extending downwardly from the wall of its inlet casing and is mounted on further support means comprising a foundation pad or piling whereby the turbine assembly in use will transmit static and dynamic loading to the bed of the water source via said support structure, the outlet end of said inlet casing is provided around its mouth with an annular radiussed, or coned, spigot designed to be fitted against a co-operating bearing surface formed around the inlet end of the draught tube to provide an articulated, releasable connection, and wherein locking means are provided for effecting said releasable connection.
